Sound Stones on the Geological Adventure Trail

Why do some stones sound bright and some dull? You will find out the answer at the Klangsteine station. When you throw a rock into the water, you'll see ripples spreading around where the rock meets the surface. It is similar with sound. When you hit a rock with a hammer, a sound wave propagates inside the rock. If it is finely crystalline or homogeneous, you will hear a bright sound. If there are crystal boundaries or microcracks that impede the propagation of the sound wave, a muffled tone is heard. Try it now!

Why do some stones ring and others remain dull? Here you will find the answer and can try it out on particularly large stone specimens.

Well done, even if you have to listen carefully ... :-)
